We spent 6 weeks staying at Sarah and Kiats apartment. The place was perfect and was kitted out with everything you need to make your stay comfortable! The apartment was spotless and had satellite tv with English channels too.
The complex has a pretty well equipped gym and a nice rooftop pool for those hot Bangkok days!
Sarah and Kiat weren't there for our stay but were always easy to contact if we needed help or advice with anything. All the staff in the apartment from the security to the cleaners were all really friendly too.
The apartment is a little bit out of the way but just outside the apartment a songthaew runs every 10mins (only 7 baht) and brings you to kaset junction where you can get buses to anywhere you want.
There's also bars and restaurants within a 10 minute walk from the apartment if you want to stay local.
Overall I'd definitely recommend this apartment to people if staying in Bangkok for a while because after staying in a few different apartments in Bangkok at different times I don't think you'll find a better one for the price!
